I figured out the problem. My shutter speed was set too low. Turns out it needs to be double the frame rate in order to achieve a smooth motion when interpreted to 24 fps. Should have thought of that before I shot. Oh well. Lesson learned.
If I read this right, you want to watch your 120fps videos at 0.25 their real speed, seeing every single frame but at 30fps. That's what I do (GoPro 3+, 720p, 120fps) but it's a bit involved. I use Blender video sequence editor. It's not intuitive but a good tutorial can make all the difference in the world, I learned with Mikeycal Meyers' tutorial: ...
Looks like you will need to transcode all clips with frame rates not matching the project's frame rate: If the frame rate is of a clip is not compatible with your project, it displays in red. You will be unable to import the clip into your project. Clips with incompatible frame rates may be playable in a new project set to the same frame rate as ...
Since this has worked with Canon footage in the past, my best suggestion would be to import your a7s footage into a 59.94 fps sequence in Premiere, export that sequence (in 59.94) in a universal format like H.264, then re-import that clip to Premiere and try slowing it down to 23.976. My guess is that Premiere isn't playing nice with whatever codec/format ...
You can use the Time Remapping effect, and just use keyframes to ease in/out of different speeds. https://helpx.adobe.com/premiere-pro/using/duration-speed.html
